The _abdomen_ is of an elongated, or cylindrico-ovate form, of a dull drab-yellowish colour, with a central, longitudinal, irregular, rather chocolate-brown bar on its upper side, and 6 to 7 well-defined lateral oblique slightly curved lines of the same colour and touching the central line; between these lines are some other irregular, but similarly coloured, markings. The sides are almost immaculate, and the underside quite so; the spinners are ordinary. About 10 examples (all immature) were found at Montpellier in branched tubes closed at the entrance with a wafer-lid. The branch arises some way below the entrance and runs up to the surface at an acute angle with the main tube; there is no lower door, and thus this tube forms the type of a new form of nest, being branched, with a wafer-lid, but without a lower door. This species cannot be confused with _N. cæmentaria_, which is found abundantly in the same locality; both the general form, colours, markings, and nest readily distinguish it from that species. _Habitat._ Montpellier. Nemesia Simoni, sp. n., Plate XVI., fig. A, p. 211. Adult female, length rather more than 9-1/4 lines (20 mm.). This spider is of a proportionally broader and stouter form than others of the genus _Nemesia_, and the cephalothorax (which is entirely glabrous and destitute of adpressed hairs) has the caput more rounded and elevated than in any other species of _Nemesia_ known to me, approaching _Cteniza_ in these respects. The _cephalothorax_ is oval, truncate, and about equally broad at each end; the ordinary grooves and indentations are strong; besides the groove which indicates its union with the thorax, the caput has an indented or pinched-in appearance towards its hinder part on each side. Except that this was present in all the examples examined (ten) it might have been taken to be accidental. The colour of the cephalothorax is dark brown tinged with yellow, darkest on the sides of the caput, which is divided longitudinally by a narrow, dull, orange-yellow line, and lightest on the margins towards the hinder part; the thoracic fovea is curved, but more deeply indented and the indentation is wider at each end than in other species, the ends being a little turned back: there is a single longitudinal row of long erect bristles along the central line of the caput, and a few more on the lower margin of the clypeus.
